you seem to be an Italian citizen, and I am just LOUDLY wondering if MAYBE you made a mistake at the airport, you went to the VOA counter and bought a 15-days visa-on-arrival for 2000.- THB, and entered Thailand with it. Actually, Italian passports will receive a 30 days stay permit when entering without a visa
You cannot extend the 90 days stay permit received when entering the country with a “single entry Non-Imm-O Retirement Visa” by the tourist extension of 30 days.
All you could do is exit Thailand and re-enter without a visa, if you are a citizen of a country that can get 30 days by entering visa exempt, you will receive a 30 days stamp and can extend this stay on Immigration once for 1900.- THB for 30 more days.
You can however, from up to 30 days before the 90 days stay permit expires, apply for the “1-year Extension of Stay Permit based on Retirement” if you fulfill the financial requirements .
. . . which are either a deposit of a minimum of 800,000.- THB on a Thai bank account in your sole name
or an income affidavit legalized by your embassy which proves that you earn more than 65,000.- THB per month
or, if your embassy doesn’t issue such an affidavit, a bank letter that proves you have transferred from abroad 65,000 THB onto your bank account, for 12 consecutive months, month for month
I just had a long conversation with a person who is married to a Thai wife, and who got the "1-year multi entry Non-Imm-O Visa based on marriage with a Thai" in Savannakhet a few days ago. He needed to show proof of finances. However, as he told me, while he was waiting in the queue, he was approached by an "agent" who asked him if he needed to circumvene the financial proof. He was assured by the agent that he could do so by paying 15,000.- THB (next morning pickup included) and for a "same day service" he would need extra 3000.- THB. I forgot to ask if the 5000.- THB visa fee was included in the 15,000.- THB
from Chiang Mai it is probably easiest to visit the Thai embassy in Vientiane, to apply for a 60 days tourist visa single entry. The requirements are absolutely doable (contrary to absolutely shitty requirements in Penang, Hanoi or Ho Chi Minh), however you will need an appointment with the embassy, and they require 3-4 working days for the processing. Here is the relevant webpage of the Vientiane Embassy
correct! On spot! I don't understand why some advise him to visit immigration and apply for a 30 days (touristy) extension. It is completely out of reach for him to this date
What are you trying to tell us? He will not receive a 30 days "touristy" extension, because he never was or is on a tourist visa. He needs to get out of Dodge ASAP, exit Thailand by air, pay the overstay fine of 15 or 16 x 500.- THB, get the overstay stamp in his passport and the computer entry. That's ALL that's left for him to do. There is no way he gets a 30 days extension, as well as they won't issue an "application denied you have 7 days to leave the kingdom" stamp. . . . . .once he is outside of Thailand, he is free to start any visa application process over or whatever comes to his mind
in case you stay in a hotel, the hotel will automatically register you TM30 in the online system. Once you move into a private accommodation, the houseowner or landlord will have to report you by TM30 within 24 hours of you arriving at the residence - either personally on Immigration or by the online system
